In fact, it turned out, while the Alberta Utilities Commission, which
regulates electricity in the province, has a 13-year-old database with
the records of 31,000 contacts from members of the public, not one of
those 31,000 contacts has been about the sound of operating wind
turbines. That's a very striking finding, but it lends credence to the
work of Australian Prof. Simon Chapman of the University of Sydney, who has a pending study
finding that complaints about turbine sound in Australia are heavily
focused on areas where anti-wind groups have been conducting public
campaigns.

Pembina researchers went further to unearth evidence of complaints, Mr. Thibault says, contacting:

"The operators of the wind farms did report some complaints during
operations, noting eight unique complaints, most of which were resolved
noise complaints (five), along with a few generalized complaints about
wind energy broadly.

"Only three complaints about operating wind farms came to the seven
Alberta municipalities with wind energy projects: one about ice throw
that was investigated and dismissed, one about the density of wind
turbines offering a terrorism opportunity, and one about noise, which
was referred to the operator.

"No more complaints were found with the health contacts surveyed (two
regional health inspectors covering municipal districts with over half
of Alberta’s wind energy) or the livestock contacts (five agricultural
fieldmen also covering the majority of the experience)."
